I suppose I could have been far more detailed in my post....remembering how hard it is for some to carry forward an intellectual concept.
My submission was to suggest that the 234 on a single engine does in fact have a considerable ability.
Not having a 234 Flight Manual with Performance Charts approved by the UK CAA/JARS/EASA at hand, I was not about to quote any precise numbers for all combinations of Temp, Altitude data sets and flight conditions.
Don't mix up Cat A or B and PC-1 or 2e and 2.
Note: I cannot imagine anyone getting any of all that confused, ever.
What's more interesting....I simply do not understand how the Helicopter Industry (to include the various World's Militaries) ever got along without all the bureaucracy we see today.
